Description
Technical Field
The utility model relates to a welding material technical field specifically is a flux core silver brazing filler metal.
Background
The flux-cored wire is a novel welding material, compared with a solid-core welding wire, the flux-cored wire has the advantages of high welding efficiency, flexible component adjustment, energy and material conservation, less flux consumption, less pollution, attractive weld joint formation and the like, is suitable for continuous automatic welding, and is widely applied to brazing copper and copper alloys, carbon steel, alloy steel, stainless steel and nickel-based alloys due to the advantages of proper melting point, good electric conductivity and thermal conductivity, excellent wetting and spreading performance, brazing process performance and the like. In the traditional silver solder brazing process, fluoride-containing brazing flux is usually matched to remove brazing filler metal and workpiece surface oxides, so that the wetting and spreading performance of the silver solder on the surface of a workpiece is improved, and finally a brazed joint with excellent performance is obtained.
Generally, an oxide film often exists on the surface of a workpiece to be welded before brazing, in the existing brazing method, brazing flux is added manually after the workpiece is heated, the method is high in welding cost, low in efficiency and difficult to accurately control the dosage of the brazing flux, the phenomenon that the brazing flux is added too much or unevenly often occurs, not only is a large amount of brazing flux wasted, but also the residue of the brazing flux on the surface of the workpiece after being welded is difficult to remove, the brazing flux can be automatically and uniformly added by using a flux-cored wire, the dosage of the brazing flux is effectively reduced, but the flux-cored wire with a seam commonly used in the market at present is difficult to remove the residue on the surface of the solder, the brazing flux is easy to absorb moisture, and.
The existing flux-cored wire manufacturing method mainly comprises three methods of strip coiling, hollow pipe powder filling and extrusion billet powder filling and extrusion. In the strip coiling method, the type 0 pipe seam which is not welded is easy to crack and leak powder in the coiling process, when the packaging weight is changed, products with surplus packaging weight and insufficient packaging weight can only be treated as waste products, and the flux-cored wire is inconvenient to use and easy to crack due to enough toughness when in use.
